sei-m1 No. 642,141.

To all whom it may concern Beit known that l, Grimme Krim, a citi Zen of the United States of America, residingl in the city ot St. Louis and State ol Missouri, have invented certain new and useful Improvements in Conveyers. oi which the following is a Specification.

Thin .invention relates 'to conveyors: in gein e nl. hut more particularly to :nonveyere` adapted to transpmt the products; ot' a bakery `from a baking; tloor to a packing floor, and has for its primary object to pro-I vide an improved construction, combination and arrangement of parte in devices ot' this character.

One of the .hjeets et the present invention is to provide improved means for stacking and loadingr the goods onto the couveyer.

A further object is to provide improved means whereby the conveyer will be autoi'natically Stopped for loadinv'.

Another object is to provide, in conibii'nition with the aforesaid conveyor. improved means 'lfor unloading the wares; therefrom while in motion, and ,for conveying;I said `oodel away from the point at which they are unloaded.

Another object i to provide an. impro' al timing device ,tor governing the relative :ur-- cessive movements of a pair of intermittently nl ovahle conveyors.

Another object is to provide improved means for starting the conveyere` attrr 'they have been brought to rest.

`lVith these and .other objects in view, as

will appear in the specification and on the drawings 'forming a part thereof, niy invention consists in the various combinations and arrangen'ients o'l" parte srt lorth `in the uppended Claims.

In the drawings: Figure l is a side elevation in the upper end ot my iniproveil device. Fig. 2 .is a side elevation ot tho lower portion ol' the saine.

Referring lnore particnlarlyto the drawings in which .my invention in excniplilied in its adaptation to the couveyiiu;i und pucle aging of craehers. and tiret of alll to Figs. l and Q o'l`: Said drawings. niy invention eontemplates a stacking; and loading;r device; a vertically movable conveyor; a horizontally movable conveyor' worhing in conjunction with the tiret Huid convey '3 a. timing device g the relative operations ot the r.onveycr=-:; and an unloading device, These several parte` ot the machine u'ill be described Separately.

Stu/'Zing and loading Zee/oe.Referring to Figs. l. il to t3, und l) to ll, a 'toed table l, which may be rigidly mounted in any suitable inaunrr lint is preferably secured to the strmctural vvorlr rforminor the conveyor Shaft to be hereinafter referred to, is supported by struts Q. Said table, shown best in Figs. 5, l) and Ll), coinprisee4 a bottom pan with r. laterally tnrnedfllange 3 on either eide. and an angle iron jl- Secured to the llange Il. Huine'ingly connected with the lorwnrd edge olf the luhlc lv by lucana. of hinges l in u bridge plate T lor liridging` the gap between thi.l table 1 ond each of; `th(I con vryrr trays lo be re'lferred to hereinafter.

(lu the horizontal flange oll cach angle bar l in slid-ably mounted a carriage lloclc t5 which is provided with an inner depending guide [lange t) and an outer depending flange l0 `lroln which project journal pins il for journalingT the rollersl l2 which serve to .retain the carriages 8 against upward dis-Y placement when they are operated in a inunncr to he presently described. Projecting upwardly 4from the carriage t5, are a pair of Fig. l hearing lugs 1? within which is secured an Loeeaioo locking disks 168 and 164 'which are keyed to the shafts 151 and 79, respectively. The beam 157 is :mtomatically locked in either position iin which it happens to be in the manner now to be pointed out.

lil/hilo the paris are in thc position lshown in Fia. 8. the periphery oi the lock disk 163 will prevent any change in position of the beam 157 after the notch lo?, has pas f out of register with the tooth 160, ln inc Same manner when the tooth 1G() is Formal into a notch in the dish 10B, the periplua'y of the disk 1li-fi.- will maintain it in that position. iirormaflly, tho beam 157 tenda to assumo the position aimwu in Fig'. 5h for which purpose lucana fi'or d rowing thc iight-A liand arms downwardly is provided by a weight 165 suspended by a link 1Go `from said arm. Under the action. oft this weight, when the mutilated gear 14S) has just con ple'ted a quarter rotation oilv the gear 155, and passed out of imesh` the tooth 161 on the lei't-hand end ot the arm 157 registers with a notch 162 in the disk lof-t whereupon the weight 165 forces the tooth 161 into said notch and thc dish 162 released and the motion of gear 1119 ifs imiairled to gear 15? 'to drive the lower conveyor in the manner already pointed out.

As the rotation of the mutilated gear 1119` continues7 a pin 167 which projects laterally ilrfirciiroim is brought into engagement. with the end oi a lever 168, 'which is prirvii'led with a journal pin 169 oscillatably mounted in a pedestal 170. Adjacent the outer end of the loyer arm 1653 piyotally connected the upper end of a connecting link 1.71, said link being pivotally connected at 172 with the righidiand arm of the beam 157. lVheiL therefore, the pin 167 impingcs the and oi the lover 16S, which engagement occurs after die gear 153 has been rotated one half of a revolution, the tooth 161 is forced iflownwardly to release the gear 155, and the tooth 1G() is iiforced upiwlrdly to engage the disk 163 By means of this nmatructiom motion is iinpznied in successive etages lo both the vertical conveyor and the hormniinl, conveycn the 'vertical conveyor being lei't re showi iu Jig. 1, and being in motion for the unloading operation, as is shown best in Fig, 7. On the other hand, by means of this gearing and the relative position of 'the parts ol the conveyor, the vertical conveyor is in loading position and held stationary just subsequentn to the unloading of the con- 'veyer pan, asshown in Fig. 7 the righthand loaded pan being therefore suspended stationary to permit 4the goods 105 to pass thereunder without interference.

fhould `it bc desired to have the vertical convey( automaiically set in motion 'by the loading movement. means are lprovided 'whereby this` may be done. For tais pur- 'lor the loading operation, as

posel a lever arm 173 may be keyed to the shai't to which the, throw lever 17 is also keyed. Secured to the :forward end oi" the lever arm 173 is a cable 174- which passes upwardly over a pulley 175 carried hy a bracket 17C; said cable being secured io the extremity oi an oli'act portion 177 of a rocli'ing lever 178. Said rocking lever is pivoied at 179 within a, bearing block 180, and is pri'widcd with a projection 181 bcia'orn which and a projection 189, on the i' amcwcrlc. is provided a tension spring 183 for imparting a normal tendency to hold thf rocking' icrer 1.78 in the position shown in i-"ig. 1. 'l'ho lover 17S, as shown best in Fig'. ly is adapted lo impinge directly upon the clasp release 15)(3 so that when the throw leier 17 is thrown forward, the arm 173 draws down upon tho cable 174i and throws the lover 17 against thc clasp release 136 to operaie it in the manner already pointed out.

'peculiar ai'lvantage resides in the time mechanism control of the vertical and horizontallconveycrs, in that while the vertical conveyor is traveling a distance equal to the apano bet'wccn two pans, one of the pans iS hoingiunloadcd and another is being brought intoydosii'ion to be loaded. llnmediately after this intermittent` min/lament oi the Verticalrconrcycr, it held stationary during lhciloading movement while at the same. time the 'horizontal conveyor makes a orward movement to carry the unloaded crackers out from 'underneath the next loaded pau, During this forward movement of `the lmrizonial convcycn the pan which is being loaded is hold stationary until after the stacking and loading .frame has been retracted, when the vertical conveyor is free, lo make a further movement.
